Replace veristat's per-program object re-opening with bpf_program__clone(). Previously, veristat opened a separate bpf_object for every program in a multi-program object file, iterated all programs to enable only the target one, and then loaded the entire object. Use bpf_object__prepare() once, then call bpf_program__clone() for each program individually. This lets veristat load programs one at a time from a single prepared object. The caller now owns the returned fd and closes it after collecting stats. Remove the special single-program fast path and the per-file early exit in handle_verif_mode() so all files are always processed. Split fixup_obj() into fixup_obj_maps() for object-wide map fixups that must run before bpf_object__prepare(), and fixup_obj() for per-program fixups (struct_ops masking, freplace type guessing) that run before each bpf_program__clone() call.
